Application June 29, 1931, Serial No. 547,671

1 Claim. (01. 36-60) The present invention is designed to improveclimbing hooks. One of the purposes of the invention is to so form thetread of the hook with relation to the shank as to ease the support forthe wearer. Another object is toso arrange the shank with relation tothe tread as to retain the shank in proper relation on the leg of thewearer. Another feature of the invention is the arrangement of the shankso as to more nearly fit the contour of the leg of the wearer. Anotherfeature of the invention is the provision of means to prevent theclogging of the spur so as to prevent its proper engagement with a pole.Further features and details of the invention will appear from thespecification and claim.

A preferred embodiment of the invention is illustrated in theaccompanying drawing as follows:--

Fig. 1 shows a side elevation of the climbing hook in place on the footof a wearer.

Fig. 2, a front elevation of the hook.

Fig. '3. an enlarged perspective view of the spur detached.

Fig. 4, a section on the line 4-4 in Fig. 2.

Fig. 5, a section on the line 55 in Fig. 2.

Fi 6, a bottom view of the tread.

Fig. 7, a section on the line l'! in Fig. 6.

l marks the tread of the climbing hook and 2 the shank. The shank isprovided with the usual loop 3 at its upper end through which a strap 4is passed, the strap being provided with a pad 5.

The inner surface of the shank is preferably concave at 6 as shown inFigs. 4 and 5. This not only strengthens the shank, but makes it morenearly conform to the leg of the wearer and consequently is less apt tochafe the wearer.

The shank has a spur 1 arranged at the usual location and the inner partof the shank has an up-turned portion 8 with a strap loop 9 throughwhich a strap 9a is passed.

The shank has an ofi-set l0 carrying the main part of the shank to therear of the tread and 5 the spur l is also off-set being arranged in theoff-set portion. In consequence of this construction the shank propertends to remain in alinement with the leg. When the shank is extendeddirectly upwardly from the tread it has a tend- 10 ency to swing back onthe leg and this is not a desirable position.

The tread is wedge-shaped with the thin edge I l at the front. Thus thethickened portion engages the heel and is of sufficient engaging surl5face to prevent injuring the heel under the shock of use. On the otherhand, the thin portion hugs the shank of the shoe and thus does notpresent an obstruction.

The spur I has a small rivet projection I2 20 which extends through theshank by means of which the spur is secured to the shank. On theunder-side of the spur there is a cutter l3 arranged in the crotchbetween the spur and the shank, the purpose of which is to cut any ac-25 cumulation of fiber from below, thus preventing the clogging of thespur. By reason of this cutting device, the spur is kept clear so thatit may readily engage a pole. Preferably the spur is slightly inclinedtoward the front. In this way 3 it is more readily driven into the poleand presents a slightly cross direction on the pole giving a moredefinite support.

What I claim as new is:

A climbing hook including a tread plate; a 3 shank extending from saidtread plate; a spur on the shank; and a cutter in the crotch between thespur and shank.
